android 获取gpu内存使用率

要获取Android设备上GPU内存使用率，可以使用以下步骤：

1. 在Android Studio中打开您的应用程序项目。

2. 在项目中添加以下依赖项：

dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:support-annotations:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:cardview-v7:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.android.support:multidex:1.0.3'
    implementation 'com.google.android.gms:play-services-ads:17.2.0'
    implementation 'com.google.android.gms:play-services-vision:17.0.2'
    implementation 'com.google.android.gms:play-services-location:16.0.0'
    implementation 'com.google.android.gms:play-services-maps:16.0.0'
    implementation 'com.google.android.gms:play-services-auth:16.0.1'
    implementation 'com.google.android.gms:play-services-identity:16.0.0'
    implementation 'com.google.android.gms:play-services-games:16.0.0'
    implementation 'com.google.android.gms:play-services-drive:16.0.0'
    implementation 'com.google.android.gms:play-services-plus:16.0.0'
    implementation 'com.google.android.gms:play-services-panorama:16.0.0'
    implementation 'com.google.android.gms:play-services-nearby:16.0.0'
}

3. 在应用程序中添加以下代码：

private double getGpuUsage() {
    Process process = null;
    double gpuUsage = 0.0d;
    try {
        process = Runtime.getRuntime().exec("dumpsys meminfo");
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()), 1024);
        String line;
        int index = -1;
        while ((line = reader.readLine()) != null) {
            if (line.contains("Graphics")) {
                index = line.indexOf(":");
                gpuUsage = Double.parseDouble(line.substring(index + 1, line.length() - 1).trim());
                break;
            }
        }
        reader.close();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (process != null) {
            process.destroy();
        }
    }
    return gpuUsage;
}

4. 调用此方法以获取GPU内存使用率：

double gpuUsage = getGpuUsage();

5. 您可以将此值打印到控制台中，也可以将其发送到您的服务器以进行分析和监控。
